PURPOSE: To obtain a nonwoven fabric which has an organic fiber layer in spite of being a light-weight inorganic fiber nonwoven fabric, high interlayer strength between the inorganic fiber layer and the organic fiber layer, excellent dimensional stability in the case of forming a laminate such as a floor material for building by providing a synthetic resin layer and causes no warpage to be an obstacle in application, and to provide a method for producing the same. CONSTITUTION: The method for producing the nonwoven fabric in which the inorganic fiber layer and the organic fiber layer coexist in an interface for bringing the inorganic fiber layer into contact with the organic fiber layers comprises applying an organic fiber-containing dispersion to a wire cloth, dehydrating the applied organic fiber-containing dispersion layer through the wire cloth, applying an inorganic fiber-containing dispersion to the dehydrated organic fiber-containing dispersion layer, dehydrating the organic fiber-containing dispersion layer and the inorganic fiber-containing dispersion layer applied to the organic fiber-containing dispersion layer through the wire cloth to form the organic fiber layer and the inorganic fiber layer.
